Semi Automatic Isobaric PET Bottle Filling and Capping Machine
The Semi Automatic Isobaric Filling and Capping Machine is built for liquids packaged in PET bottles, using isobaric filling to complete both filling and capping on one machine. The operator handles loading, transferring and removing bottles while the filling and capping cycle runs automatically, making it suitable for small production lines, pilot lines, back of store production and startup brands. It is manufactured to beverage hygiene requirements with the frame and wetted parts made of SUS304 stainless steel.

Application Scenarios
Microbreweries & Craft Brands – Bottle IPA/Lager/Stout/Wheat for local bar, restaurant & bottle shop distribution.
Brewery Taprooms – Small-batch bottling of seasonal or limited-edition releases.
Contract / Pilot Bottling – Flexible head count scales with trial runs or outsourced packaging.
Export Market Breweries – CE-compliant electrical brands accepted in EU/US/AU/UK markets.
Technical Specifications
| Item | Specification |
| Filling Heads | 4 / 6 / 8 / 10 (customizable) |
| Capping Heads | Same as filling heads (monoblock or separate capper optional) |
| Filling Method | Isobaric / Counter-Pressure – CO₂ purge → equal-pressure fill → snift |
| Beer Loss | < 0.3%–0.5% (Negligible) |
| Production Capacity | 4-head: ~200 b/h; 6-head: ~300 b/h; 8-head: ~400 b/h; 10-head: ~500–600 b/h (500ml, cold beer 0–4°C) |
| Material (Wetted Parts) | SUS304 stainless steel, mirror polish Ra ≤ 0.8 μm |
| Frame / Non-Wetted | SUS304 brushed finish |
| CO₂ Pre-Evacuation | Single or double CO₂ purge before filling (programmable) |
| Filling Valve | Long-tube mechanical isobaric valve, no-bottle-no-fill sensor |
| Control System | Siemens S7 PLC + Siemens Color Touch HMI + ABB Inverter + Schneider relays & breakers |
| CIP Function | Dummy bottle / dummy cup CIP port, filling bowl & lines flushable |
| Bottle Infeed/Outfeed | Conveyor with star wheel (linear or rotary style per model) |
| Power Supply | 1-phase or 3-phase 220/380/415/480V 50/60Hz (customizable) |
| Air / CO₂ Requirement | Clean dry air 0.6–0.8 MPa; CO₂ 0.2–0.4 MPa |
| Beer Feed Pressure | From Bright Beer Tank 0.1–0.25 MPa |
| Certification | CE / ISO compliant |
Key Features
01
True Isobaric Counter-Pressure Fill
CO₂ replaces air in bottle before filling at equalized pressure → minimal O₂ pickup, preserves carbonation & aroma.
02
Global Premium Electrical Brands
Siemens PLC & Touch Screen, ABB VFD, Schneider components → easy local service & spare parts worldwide.
03
Configurable Head Count (4–10)
Scale capacity exactly to your brewery's weekly bottling volume.
04
Magnetic Crown Capper
Adjustable torque prevents cap deformation yet ensures leak-free seal.
05
No-Bottle-No-Fill & Broken-Bottle Protection
Photoelectric sensors stop filling/capping when bottle absent or broken.
06
CIP-Ready Design
Recirculate caustic/acid through filling bowl & valves via dummy cups; no disassembly needed.
07
Low Foam / Low Loss
Vent-tube level control + controlled pressure release keeps product loss negligible.
Product Advantages
| Advantage | Explanation |
| Preserves Beer Quality | CO₂ pre-purge + isobaric fill keeps dissolved O₂ < 50 ppb → longer shelf life & fresher taste. |
| Minimal Product Waste | <0.5% beer loss → saves hundreds of liters annually on premium craft beer. |
| Scalable Throughput | Choose 4–10 heads matching your bright tank volume; upgrade later by adding heads/modules. |
| Trusted International Components | Siemens/ABB/Schneider = fewer breakdowns, easier customs clearance, local tech support. |
| Compact Footprint | Linear semi-auto or small rotary monoblock fits limited floor space in craft breweries. |
| Versatile Packaging | Handles beer + any carbonated beverage in standard crown-cap glass bottles. |
| Fast ROI for Small Breweries | Automates bottling vs manual counter-pressure fillers → frees labor, increases daily output. |
